this below is my pod file :

platform :ios, '10.0'

target 'weather' do
  use_frameworks!
  pod 'Kingfisher'
  pod 'Alamofire'
  pod 'Firebase'

end

KingFisher and Alamofire install successfully but Firebase does not

Your podfile is ok, but there seem to have been some network issue while you ran pod install/update. Do the following to solve this issue:

1. pod cache clean --all
2. pod update
